Abstract
The present invention provides a lock-up clutch for a torque converter. The lock-up clutch includes an outer carrier, an inner carrier, a first friction plate, a rotation of which is restricted by the outer carrier, and a second friction plate, a rotation of which is restricted by the inner carrier. All key grooves of the outer and inner carriers are opened in two radial opposite directions, and flow path grooves defined between friction members attached to the friction plate are aligned with circumferential positions of keys of the friction plate. Therefore, oil for cooling a clutch pack may smoothly flow through the inner carrier, the flow path grooves, and the outer carrier.
